# Installation
## Distribution channels
### NPM Registry
We publish single module to npm: [swagger-client](https://www.npmjs.com/package/swagger-client).
`swagger-client` is meant for consumption by any JavaScript engine (node.js, browser, etc...).
The npm package contains transpiled and minified ES5 compatible code.
```shell script
$ npm install swagger-client
```
**Increasing installation speed:**
`swagger-client` integrates with [ApiDOM](https://github.com/swagger-api/apidom) and use it
as a direct dependency. Some transitive dependencies of ApiDOM are [optional](https://docs.npmjs.com/cli/v8/configuring-npm/package-json#optionaldependencies),
which means you can run `npm install --omit=optional` to speed up the installation:
```json
"optionalDependencies": {
"@swagger-api/apidom-ns-asyncapi-2": "^1.11.3",
"@swagger-api/apidom-ns-asyncapi-3": "^1.11.3",

"@swagger-api/apidom-parser-adapter-yaml-1-2": "^1.11.3"
}
```
> NOTE: When ApiDOM optional dependencies fail to install, you can safely ignore it as `swagger-client` can work without these optional dependencies.
After installed successfully:
[ES6 imports](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import)
